featuress/changelog: On snapshot, notify irrespective of failures

During snapshot, changelog barrier is enabled and a
explicit rollover of changelog is initiated. During
rollover of changelog, if any error or changelog is
empty, the notification was not sent to reconfigure
and hence snapshot was failing because of timeout.
This patch addresses it by sending notification
irrespective of failures and sends error if any
back to barrier.
